This biological evaluation analyzes the potential impacts to U.S. Forest Service (Forest Service) and Bureau of Land Management (BLM) Sensitive wildlife and plant species from the proposed Rosemont Copper Project (project) in the Santa Rita Mountains on lands administered by the Coronado National Forest (the Coronado), BLM Tucson Office, and Arizona State Land Department (ASLD), as well as private landowners. This project may result in impacts to numerous Forest Service and BLM Sensitive species. Thus, all the potential impacts from this project are evaluated for all species on the 2007 Coronado National Forest Sensitive Species lists (Forest Service 2007a, 2007b) and the 2005 BLM Tucson Office Sensitive Species list (BLM 2005). See appendix A for the species lists.
